Product Summary
The LISTRONG 9DST is an intermediate wire drawing machine built for bare copper wire. Copper rod enters at Ф2.5–Ф3.0 mm and leaves as finished wire between Ф1.0 mm and Ф2.8 mm, drawn through nine dies on two horizontally arranged shafts. Maximum mechanical speed reaches 1200 m/min, and the machine holds 1000–1200 m/min on Ф0.8–Ф1.5 mm wire, 800–1000 m/min on Ф1.5–Ф2.0 mm wire and 500–800 m/min on Ф2.0–Ф2.78 mm wire. An AC 55 kW induction drive motor and an AC 11 kW spooler motor work with variable frequency control and a tension system that automatically tracks drawing-speed changes, keeping outer diameter tolerance extremely small and the wound wire smooth and compact. The 9DST is named in a CE certificate issued for the EU market under EN ISO 12100:2010 and EN 60204-1:2018/A1:2025.
Key Features
1200 m/min maximum mechanical speedNine dies on two horizontally arranged shafts deliver high output, with a speed band per finished diameter so you can match throughput to your product mix.
AC 55 kW drive and AC 11 kW spooler motorsVariable frequency control with dual VFD/servoir drive technology supports high-speed yet stable production across the shift.
Precise tension control systemTension is tracked automatically as drawing speed changes, helping hold an extremely small outer diameter tolerance and producing smooth, compact wiring.
Servo traversing with limit detection switchSpool build stays even from flange to flange, reducing manual adjustment between bobbins.
Fully immersing lubrication at 150 L/minDie and wire are continuously flooded, supporting consistent surface quality on bare copper.
CE conformity for the EU marketCertificate CE-JL26020401-AL-MD issued by ICG to EN ISO 12100:2010 and EN 60204-1:2018/A1:2025, issued 2026-02-10.

Models and Options
The 9DST is configured around a nine-die, two-shaft horizontal drawing line for bare copper. Two die holder dimensions are accepted — Ф28 mm × 15 mmT or Ф25 mm × 15 mmT — and the nine drawing dies themselves are supplied by the customer, which lets you keep die geometry matched to your own wire program.
The same CE certificate also covers other LISTRONG models, including 17DST, 13DST, 14DT, 22DTA, 24DT, 24DW, 26DW and the WDF450 and LHD450 series. Ask our sales team for the specification of the model that matches your inlet and finished wire sizes.
Materials and Structure
The 9DST is built in steel with two drawing shafts in horizontal arrangement and nine die positions in series. Lubrication is handled by a fully immersing system sized for 150 L/min oil flow, so dies and wire stay flooded through the pass line. Wire take-up uses a servo-driven traversing unit with a limit detection switch, and the operator side is closed by a sliding safety door. The cooling water circuit is specified at 0.2–0.4 MPa, ≤25 °C, pH 7–8 with 420 L/min flow and must be free of suspended solids, minerals, metal impurities and corrosive substances.
Applications
The 9DST suits bare copper wire drawing in wire and cable manufacturing, metal product processing, and hardware standard components production. Because it is an intermediate machine, it takes rod from Ф2.5–Ф3.0 mm down to the intermediate range of Ф1.0–Ф2.8 mm. LISTRONG also manufactures annealing machines and wire bunching machines for bare copper, copper alloy and stainless steel wire, so the 9DST can be planned into a wider line layout.
Customization
Machine-side adaptation starts with the die holder: select the Ф28 mm × 15 mmT or Ф25 mm × 15 mmT die size and supply your own nine dies. Before an order is placed, our engineering team confirms your incoming rod diameter, required finished diameter and wire type against the 9DST speed bands. For any configuration question outside the published specifications, contact our sales engineers directly rather than assuming a value.
Frequently Asked Questions
Which wire diameters can the 9DST draw?It draws bare copper from an inlet of Ф2.5–Ф3.0 mm to a finished wire of Ф1.0–Ф2.8 mm, using nine dies in a two-shaft horizontal arrangement.
What drawing speed can we expect?Maximum mechanical speed is 1200 m/min. Published bands are 1000–1200 m/min for Ф0.8–Ф1.5 mm, 800–1000 m/min for Ф1.5–Ф2.0 mm and 500–800 m/min for Ф2.0–Ф2.78 mm.
